I said the EII had lower axial aberrations (spherical and chromatic). High aberrations seem to affect how clean and sharp an image looks well before a loss of resolution can be seen, especially at low magnification.To see what I mean try comparing the images in the post below:<a href="http://www.birdforum.net/showpost.php?p=3424981&postcount=17" target="_blank">http://www.birdforum.net/showpost.php?p=3424981&postcount=17</a>At the proper distance from the computer you can see that both binoculars easily resolve line pairs smaller than anyone's eyesight acuity, and yet even the largest element on the chart looks clearer and sharper in the Zeiss image, because its aberrations are lower. That's why I use the Zeiss as a universal reference for binocular image quality. It's just too hard to judge the absolute image quality of any "good" binocular without a reference image of known high quality for comparison. Henry</blockquote>
